The wait is over: The fourth Step Up installment (in 3-D, of course) is here! StepUp Revolution takes the fiercest dancers to the streets of Miami. Calling themselves The Mob, these hip hoppers, breakers, poppers and lockers use flash mobs to take down a wealthy businessman who’s threatening to destroy their neighborhood. Dance celebrities on set included Mia Michaels, tWitch, Misha Gabriel, Phillip Chbeeb and more. And one of our favorite former “So You Think You Can Dance” contestants, Kathryn McCormick, makes her acting debut as leading lady Emily! She dances opposite hunky Ryan Guzman, also a Hollywood newcomer. DS caught up with McCormick about her exciting first experience starring on the big screen.

Dance Spirit: How’d you land this awesome role?

Kathryn McCormick: It was the first acting audition I’d ever been on, and it was intimidating. When I get nervous, I ramble on and on, so afterward I felt completely embarrassed. But I kept getting callbacks! When I got the call saying I’d won the part, I was on the way to assist “So You Think You Can Dance.” I was in shock. I called my mom crying. She was like, “Did you get in a wreck? Are you okay?” I said, “I got the lead in the movie!” Then she started crying, and we had to hang up because we couldn’t understand each other. It was funny.

DS: Tell us about your relationship with co-star Ryan Guzman.

KM: Before this movie, Ryan had acted, but he had never danced. I think my time on “SYTYCD” helped me, because I’ve been in the position of working with someone who isn’t as experienced in a certain style. We connected as soon as we met, and we came to be really comfortable with each other. I helped him dance, and he helped me act.

DS: Do you have a favorite scene?

KM: My heart is in the contemporary duet with Ryan choreographed by Travis Wall, because that’s my style. But the most fun day for me was when we filmed Emily’s initiation into The Mob. It’s when you see her rebellious side come out for the first time. She’s dancing on tables in a restaurant, and she has a dress, mask and heels on. It was so much fun to be tossed around from dancer to dancer.

DS: What’s next for you? More movies?

KM: I don’t know where my life is going, but it will always have dance in it. I’m in acting classes, and I’m going to both acting and dancing auditions. On top of that, I’ve been doing a little motivational speaking. I’m not one to make too many plans, because so often, the things that actually happen are greater than anything I could have imagined. If you had asked me five years ago what I’d be doing, this wouldn’t have been on my list. I just put in the work, leave my heart open and see how it all lines up.
